Something Weird?

Last night during a FFA match I saw a fully decked out Ares player using Zeus' magic, relics, and items. I thought he may have had the armor of Morpheus on at first until he got a brutal kill on me and I'm certain he was in full Ares armor.

Saw this guy use the Lightning Vortex magic and Zeus' shield (which glows yellow and Ares glows redish). I'm positive that this shouldn't be possible.
